Far-infrared laser magnetic resonance spectrum of34S16O in X3Σ− state

The far-infrared laser magnetic resonance spectrum of34S16O in the ground X3Σ− state has been observed using five optically pumped laser lines as sources. The isotopic sulfur monoxide radical was produced by the reaction of oxygen gas with sulfur vaporized from an oven. The construction and design of such an oven have been discussed. A merged least squares fit of the earlier EPR and microwave results, and the present data yield better-determined molecular constants.
